Acertain radioactive (parent) nucleus transforms to a different (daughter) nucleus by emitting an electron and a neutrino. the parent was at rest at the origin of an xy coordinate system. the electron moves away from the origin with linear momentum (-5.6 x 10-22 kg m/s) ; the neutrino moves away from the origin with linear momentum (-6.9 x 10-23 kg m/s) . what are (a) the magnitude and (b) angle (from the +x axis) of the linear momentum of the daughter nucleus? (c) if the daughter nucleus has a mass of 8.7 x 10-26 kg, what is its kinetic energy?
